Heaters in Tents: The Carbon Monoxide Rules
Carbon monoxide is a colorless, odorless gas made by anything that burns fuel, and it can build up quickly inside tents, campers and vehicles. CPSC and CDC guidance says to keep fuel-burning heaters, stoves, lanterns and grills out of enclosed shelters. Staying warm on a cold night is mostly about your sleep system, dry layers and food, with a battery CO alarm as a backup, not a permission slip.
